Be it known that l, @sonn Funnier.

Homunnne, a citizen of the United States, residing at Chicago, in'the county of Cook and State of Illinois, have invented certain new and useful Improvements in Egg-Dipping Machines, of which the following is a specification.

My invention relates to egg-preserving means and has particular reference to an apparatus for dipping eggs in lar e quantities in a preserving or treating fluid and for automatically timing the duration of the dipping process. With these general objects in view my invention consists in the novel construction of machine hereinafter described in detail, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.-

In the drawing 7 Figure 1 is a perspective view of a machine embodying my invention.

Figure '2 is a section taken substantially on the line 2-2- of Figure 3.

Figure 8 is an enlarged detail View taken from Figure 1.

Figure ,4 is a section taken substantially on the line Hot Figure 1, partly broken away, drawn to an enlarged scale.

Figure 5 isan enlarged face view of the trigger and associated mechanism shown in Figure land substantially an elevation of the details shown in Figure 1.

The frame of the machine herein shown, which may be varied in any suitable way, consists of a series of uprights or posts 2, 3,4, 5 and 6 and horizontal bars 7, 8, 9land 10 mounted on posts 11 and 12 and on the uprights 5 and 6 and all supportedon a'base l3. The frame members may be angle irons" such as 5 and 6 shown in cross section in Figure 4:, which for the members 7 to 10 provide framedikeledges 15, 15 adapted to support liquid-containing trays or tanks. Provision is made for two'suchdipping trays for the purpose oijthe present illustration of my invention, by dividing the space I formed within the members 7 to 10 by a pair of similar angle irons 16 and 17. The spaces 18 and 19'thus produced may in a simple manner for the present purpose represen-tdipping tanks, or skeletonstherefor, or the relation or position of such tanks with reference to the remaining portions of the machine herein shown." 20 represents 'a movable section of track, theremaining por- Specification of Letters Patent.

tion of the track (not shown), beingfixed or immovable and a continuation of the movable'section 20 in its normal position shown in full lines-1n Figure 1.

The track section 20 is mounted on an arms orlever 21 which is pivoted at 22 between the parallel flanges bearing the numerals 5 and 6 in Figure 4:, which in Figures 1 and 4 represent a pair of uprights, angle iron,

posts, or standards. 'On the, arm is mounted in any suitable manner a counter weight 23 which may be made adjustable along the arm to vary its leverage according to requirements. A stop 24 "(Fig 4) between the standards 8 and l'limits the downward movement of theit'ree end of the arm or lever 21, which end is free'to swing in a slot or opening 24 formed byspacing apart the frame" standard consisting of the pair of angle irons 3 and 4. Egg-containers, not

shown, are hung from trolley wheels or grooved rollers on the track and when on the'movable section 20 of said track are dipped into the tanks represented by the framed spaces 18 and 19, and one'of the ob} jectsof thehereinafter describedmechanism is to accurately time the dipping automatically, which is necessary, especially where the liquid is heated to a high temperature. The arm 21 and its tracksection 20 is swung down to the dotted lineposition shown in Figure 1 to dip the load on said track section (not shown) first, say, in the tank 19 and then in the tank 18, by means of a foot lever 25 that is pivoted at 26 between the standards 5, 6 and 3, 4-. This foot lever is connected with the arme21 by 1 means of a connecting-rod 27 the ends of which are pivoted at 28; and 29 to the arm 21' and the lever 25, respectively.

Provision ismade to catch and hold raised the free or rear-end of the arm 2-1'i'or the v required length of time in the dotted line position and to hold the track section 20 with its load lowered into the dipping tank 18 or 19; The mechanism vforthis purpose consistsof'a catch or latch 30 that is pivoted at 31 to a plate 32 hung for free swinging movement on a pivot 33 mounted on the standard 3. "On theplate 32 is a stop pin .3!

which limits thedownward movement of the latch *30 and holdsitfin its normal position across the space" 24 between the standards3 and 4:, asshown in Figure 1. The latch 30 is, however movable upward to clear the space between the members 3 and 4:,or to sirnilar bore 37 in the plate 32 hanging in its normal position] The pin 35 is secured to a right angle flange 38 on a swinging member pivoted at 40 to an ear or lug 41 which projects forwardly from the member From the lower end of the swinging member 39, which is a trigger release member, projects forwardly an arm or lug 42 to which is secured a curved contact shoe or plate 43 which is engaged by the hereinafter described 1 automatic timing mechanism to swing the trigger release member. On the flange portion 38 of said member 39 is the pin or detent finger 35 which is normally engaged with the normally concentric bores 36 and 37, and when the said detent finger is; withdrawn from said bores the downward pressure of the rear or free end of the arm 21 will swing the latch 30 downward and out of the path 24 by swinging the plate 32 on its pivot 33 to the left (Figures 1, 4 and After the arm 21 has returned to its normal full lin position shown in Figure 1 gravity holds the latch plate 32 and its latch 30 in their normal aosition shown clearly on a large scale in igure 5.

The release of the arm 21 in its arrested, or dotted-line position by disengagement of the detent finger 35 which, as shown, holds the base-plate 32 for the latch 30 in normal position is effected through the contact shoe or plate 4-3 being engaged and swung out of the circular path of either one of two rods or arms 44 and 45 which extend horizontally from the respective ends of a cylinder or fluidsubstancecontainer 46 which is mounted ona collar 47 which rotates on a pair of trunnions, shafts or journals 48 and 49 whichare rotatably mounted in the standards 2 and 3. On the shaft 49 isirevolubly mounted the upper end of an arm 50. To th latter is pivoted at 51 one end of a curved connecting bar. or red 52. The other end of the connection 52 is pivoted at 53 to an elbow bearing-bracket 54that is secured to and is projected from the side of the arm 21 as shown in Figure 1. When said arm 21 is swung to its dottedline position by pressing down the foot lever 25 the connecting bar 52 will swing the arm forwardly against the rear side of the arm 45 and thereby-swing the container 46 to its horizontal or dotted line position. In this quarter revolution which carries the. contact arm 45 against the shoe 43 swinging the latter back and out of its way. thereby with-,

drawing the detent finger 35 whiclrholds the plate 32 against rotation on its pivot and permitting the arm 21 to push aside the latch 30- and its plate 32 as one member, and return to its normal position.

The container 46 is partially filled with any suitable flowing substance and is dividedby a partition 55 into two chambers 56 and 5. which communicatewith each other through valve controlled bores or ports 58 and 59. Said ports are intersected by bores 60 and61 with which valve plugs 62 and 63 have threaded engagement. whereby said plugs are adjustable into and across the paths of the bores 58 and 59 to vary the volume of flow therethrough. The chamber 5.7 in the position in which the parts are shown in Figures 1 and 3 is filled with a suitable liquid, such as water, mercury, or

any other substance adapted to pass freely through the openings 58 and 59. In Figure 1 (in which the container 46 is assumed to be made of, transparent material) the dotted line position of said container or cylinder 46 shows the chamber 57, held by its connection with the arm 21 in its raised or arrested position, elevated a little higher than the chamber 56, which. at the beginning of the elevating movement is the upper and empty chamber. This elevation of the filled chamber 57 assists theiiou" through the ports 58 and from said filled chamber to the rearward or empty chamber. IlVhen the flow has transferred the greater portion of weight of fluid to the chamber 56 the weight will be removed fromthe arm 50 on.

which th container supported horizontally by the arm 45 and the container will swing another quarter revolution causing the arm 45-to strike'the shoe 43 and reversing the positions of the chambers 56 andf57,placing the latter at the top; also substituting the arm 44 for the arm 45 as the next acting arm to operate therelease mechanism and-restoring the lever arm 21 to swing-the movable track-section into normal position and in alinement with the fixed track-section, a broken awayvabutting end of which is shown in Figure l and labeled 2 0; the obvious details of one of numerous means of track support being omitted from this fixed track portion 20 which may be continued at the left hand end (Fig. l) of the swinging track section 20, or caused to abut in the same manner as that shown for the fixed track portion20.

From the upper body portion of the baseplate 32 for the latch 30 projects a curved and pointed lug or toe portion 64: which is engaged by a stop-pin 65 that projects from the standard 3and which prevents the plate 82 from swinging back beyond normal position, or into the pathway 24! of the arm 21.

For the purpose of facilitating the flow from one of the chambers 56 and 57 to the other, provision is made to permit the air displaced by liquid in the receiving chamber to escape into gradually enlarging air space above the liquid in the discharging chamber and relieve the tendency to form a vacuum there. For this purpose a pair of oppositely projecting air-tubes 66 and 67 are mounted in corresponding bores through the partition which, as indicated most plainly in Figure 2, are arranged laterally of the valveports 58 and 59 and extend to points near the respective ends 68 and 69 of the container 46, as shown in Figures -1 and 6. In the dotted line position of the container 46 in Figure 1, as the air is displaced by liquid flowing into the chamber 56 it is permitted to escape into the air-tube 67 and into the elevated end of the chamber 57, which in Figure 3 is there the lower end. I

In operation, egg-containing receptacles are suspended from and along the stationary track 20 and successively moved onto the track section 20 into position over the first dipping tank outlined as 19, the foot lever 25 is then pressed down to its dotted line position to lower the track section 20 and dip its container into the tank 19, the free end of the lever arm 21 lifting the catch 30 against the resistance of its spring 80 anchored on a pin 30" and held against return move ment on said catch resting on its stop pin 34. The length of time that the egg container (not shown) is held in the solution in the tank 19 is automatically determined by the time required for liquid, or its equivalent to overbalance the container and swing its chamber to the position of the full line position of the chamber 57 and cause the arm 45 to swing the member composed of the elements 43, 89, 38 and 35 out of its path to disengage the detent finger 35 from the bore 37 intheplate 32. The detent finger 35 being released from the plate 82 the weight of gravity operating at the rear and free end of the arm 21 will cause it to tilt aside the V catch 80 and its plate 32 now free to swing on its pivot 88. If the eggs are to be treated a second time the egg container will be moved on thetrack section into position over the tank 18, the foot lever again pressed and the above described operation repeated. The

container may then either be removed from the dipping track section 20 or continued to the left on a stationary track 20 to some more distant point.

I claim as my invention:
